Vitamin W is
short for Wakefulness Enhancers. Wakefulness Enhancers are different from stimulants in that while stimulants give you energy, stimulants
don't give you true wakefulness, and they have a
crash or a comedown or tiredness and sometimes lower
mood. Wakefulness Enhancers
don't give you much energy, but they give you true wakefulness, and have less mood boosting effects, but no depression or low energy and instead, you get sleepier and sleep more on the comedown.
Examples of Vitamin W are: Modafinil, Armodafinil, Hydrafinil, Flodafinil (Flmodafinil), Wakix, Sunosi, Modafiendz, and more.
